The present invention related to display systems for mounting to shelving in order to display multiple products for consumers to purchase and, more particularly, to an improved roller shelf system.
It is common is display systems to arrange consumable products, such as packaged boxes or bottles, in rows across a shelf. However as each consumable product is removed, the product behind it remains in place spaced from the edge of the shelf. As more and more products are removed, the next available products is further and further away from the consumer.
In recent years, roller shelves have been installed on or in replace of standard flat shelves. Those shelves include a series of rollers that permit products in a row to roll to the front of the assembly. One conventional type roller assembly includes a spring-pusher system that urges the products along the rollers to the front of the assembly. When an item within a row is removed, the spring-pusher applies pressure to the last product in the row urging the entire line of remaining products forward.
Another type of roller assembly, sometimes referred to as a gravity-based system, involves angling the rollers downward slightly toward the front of the display. Those systems utilize gravity to cause remaining products on the roller assembly to roll forward when a product is removed.
A need exists for an improved roller assembly that provides for ease of assembly.
A roller rack assembly for storing and displaying one or more products is disclosed. In one embodiment, the roller rack assembly includes a support tray, and a roller track assembly on the support tray. The roller track assembly includes at least one roller track with a front end, a rear end, a bottom and two spaced apart side walls. A front end cap is attached to the front end of the roller track. A rear end cap is attached to the rear end of the roller track. A plurality of rollers are mounted to the roller track and arranged parallel to one another. Each roller has a substantially cylindrical roller surface with a rotational axis, and lateral sides perpendicular to the rotational axis. Each roller also has an axle extending out of each lateral side with an axis coincident with the rotational axis. Each axle is rotationally mounted to a side wall of the roller track so that the roller can rotate about its axles. A pusher mechanism including a pusher back located above the roller track and a spring mechanism biasing the pusher back toward the front end of the roller track for urging products in front of the pusher back to slide on the rollers toward the front end of the roller track.
Preferably the front end cap includes a slot that extends substantially across the end cap. The slot is configured to receive a display panel which stops or inhibits forward motion of products that are on the rollers.
In one embodiment, the roller rack assembly optionally includes a plurality of hooks mounted on the back of the support tray for securing the support tray to a structure.
Preferably the roller assembly includes one or more lateral supports that slidably attach to the roller track assembly or the support tray and are configured to be laterally translatable relative to the roller track assembly.
In one configuration, the roller track assembly includes at least two roller tracks.
Preferably the pusher back includes a pusher foot that is sized to slide within a groove in the roller track assembly located between the two roller tracks.
In one embodiment, the spring mechanism includes a torsion spring with a first end secured to the front end cap and a second end mounted to the pusher back or the pusher foot.
Preferably the bottom and side walls of the roller track define a U-shape and the front end cap and rear end cap each include laterally spaced apart sides and a base that are shaped to engage with the sides and bottom of the roller track so that the front and rear end caps are each captured within and secured to the roller track.
In an embodiment, the roller track includes a base track and a roller frame that is slidably mounted within the base track.
The roller frame may include two spaced apart frame walls, with each frame wall having a plurality of equally spaced apart holes formed in the frame wall. One of the axles of each roller is located in one of the holes in one of the frame walls and the other axle of the roller is located in another hole in the other of the frame walls. The holes are configured to permit the roller to rotate within the holes.
In one configuration the roller frame is formed with weakened points along its length that facilitate the breaking of the roller frame at those discrete locations to divide the roller frame into smaller segments.
In an embodiment, a support frame is attached to the bottom of the roller track assembly, the support frame includes brackets that attach to the bottom of the front end cap and rear end cap and longitudinal beams that are attached to the brackets for providing support.
In another embodiment a roller rack assembly is disclosed for storing and displaying one or more products. In this embodiment, the roller rack assembly includes a support tray and a roller track assembly disposed on the support tray. The roller track assembly includes at least two roller tracks with each roller track having a front end, a rear end, a bottom and two spaced apart side walls. The roller track includes a base track and a roller frame slidably mounted within the base track. A plurality of rollers are mounted to each roller track and arranged parallel to one another. Each roller has a substantially cylindrical roller surface with a rotational axis, and lateral sides perpendicular to the rotational axis. Each roller also has an axle extending out of each lateral side with an axis coincident with the rotational axis. The roller frame includes two spaced apart frame walls. Each frame wall has a plurality of equally spaced apart holes formed in the frame wall. One of the axles of each roller is located in one of the holes in one of the frame walls and the other axle of each roller is located in one of the holes in the other of the frame walls. The holes are configured to permit the roller to rotate within the holes.
A front end cap is attached to the front end of the roller tracks, and a rear end cap attached to the rear end of the roller tracks. A pusher mechanism is provided and includes a pusher back located above the roller tracks and a pusher foot attached to the pusher back and extending downward into and adapted to slide within a groove located between the two roller tracks. A spring mechanism is provided for biasing the pusher back toward the front ends of the roller tracks for urging products in front of the pusher back to slide on the rollers toward the front ends of the roller tracks. The spring mechanism has a first end secured to the front end cap and a second end mounted to the pusher back or the pusher foot. The front end of each roller track is attached to the front end cap and the rear end of each roller track is attached to the rear end cap.
